Ahhh, ummm... sorry didn't note the start time... it could of been flashing before I dragged myself out of my bed this morning
As far as I recall, I've not messed with any thresholds in this section... it was really plug and play, with only the adjustment made for height above sea level changed.
The Alarms section is a completely separate facility.
Referring to the manual – the logger display has default values already set unless you change them (the defaults are 2 and 4 respectively).
I believe (though could be wrong) the weather forecast display will flash with both arrows if the pressure changes + or – by 2-4hPa (see point 2 of manual). The down arrow will flash if the pressure drops 3-9hPa (see point 3).
Clear as mud I’d say….
A former Oregon Scientific Weather Station I had 'flashed' the weather forecast display to indicate a 'sudden' change in appraoching weather - e.g. very severe rain rather than just rain.
My Watson was also flashing this week corresponding with a sharp fall in pressure - and sure enough heavy rain soon followed!
I've taken it that the flashing just indicates severity - that said, unable to proove weather this happens for anything other than the rain display, as unlikely to experience 'severe' sun here in Scotland
I think that sometimes just the arrow flashes - my 'up' arrow is flashing now - and sometimes the whole tendency box including the forecast icon flashes.
Snap Steve - up arrow flashing here as well. Must be good news after the last few days wind and rain!
You've got me curious now - can't recall having noticed the tendency arrows ever being steady - as am working from home the next couple of days I'll keep a closer eye than usual
Have a suspicion that speed of pressure change (which might be why the pressure threshold is configurable - i.e. ability to customise the 'warning' dependent on how quickly pressure typically changes in your region) triggers whether the entire icon flashes
Ps - and unrelated (sorry) - tried to submit your user location form, but as I don't have my own website I couldn't complete all the fields. Any overrides?

I think you're right; I think they are either flashing or not present.

I'm not sure that there's any way around it; Kevin (who developed it for me and who basically runs it for me) may know. A number of people upload data to Weather Underground (or similar) sites and use their page there for the link.
